1, Claim. (01; 45-413 This invention relates to certain new and useful improvements in extension leaf tables in which the leaves are normally stored beneath the table top and adapted to be moved into the plane of the table top and into co-operative relation withthe ends of said top whereby the length of the table may be increased;

The main object of this invention is to provide means for removably supporting the table extension leaves in co-operative relation with the ends of the table top in a rigid and secure manner. V

"Other objects are to provide a construction for supporting the table extension leaves that is simple, durable and inexpensive and which may be quickly and easily manipulated to bring the leaves into and out of co-operative relation with the table top;

Other objects and advantages relating to the details of the structure and relation of theparts raised position inco-operative relation with the adjacent end of the table top.

Figure 7 is a detail vertical section taken on line 7 7, Figure 6. i

' Figure 8 is a perspective view of one of the hinge members for supportingthe extension leaves.

My invention, as illustrated in the drawings, consists of a conventional table top 1 rectan- I gular in plan view, and has secured to the underside and midway between theends thereof, -a pair of spacer strips -2 ,positioned one adjacent either vertical edge, of the table top. The spacer strips --2- are relatively short compared with the length of the table top 1-- and-may be secured thereto by any suitable means as by screws Beneath the table top -1- and between the spacer strips 2-, is positioned a slide bar supporting frame 4 which, in this instance, is composed of upper and lower supporting members 5 and 6- respectively, of substantially the same width as the length of the spacer strips 2 and-which are maintained in uniform spaced relation by a plurality of, in this instance six, guide members -7 which are secured to the supporting members5 andp6- in any suitable manner as by screws 8-.

The guide members -'7- are arranged in two sets composed of three members each, each set being positioned adjacent respective ends of the supporting members -5 and 6--,-- the members of each set being arranged in parallel spaced relation to form suitable guide slots 9 for receiving respective slide bars -'l0-- adapted to support the extension leaves, as hereinafter more fully explained.

The-slide bar supporting frame -4 is secured to the under side of the table top --1 midway between the endsthereof by screws -11jpassing through the upper supporting member -5 and screw-threaded into said table top. The table top l with the'slide bar supporting frame -4-- connected therewith, is supported upon a suitable frame ,l4- which, in this instance, is like the table top 1 rectangular in plan view but" slightly smaller in outline than said top.

' The frame 14 consists of a pair of side members 15- which extend in parallel spaced relation longitudinally of thetable top 1- and a pair of end members 16arranged tov extend transversely of the table top and across the ends of the side members --'15 to which said end members -l6 are secured in any manner wellknown to'those skilled in the art. 1

The frame,l4may;be supported by one or more legs, depending upon the desire of the Y manufacturer, but for clearness, I have shown four legs as 1'7 positioned one at each'corner of the frame in any suitable manner, not necessary herein to. illustrate. I The table top -l is mounted symmetrically upon the frame 14 and maintained in spaced relation thereto by the spacer strips 2 which rest, upon the side members 15-and to which the frame is secured in any suitable manner as by screws 18,, see Figure 2. The spacer strips 2,' as hereinbefore mentioned, are relatively table top 1- which leaves a space or opening 20 adjacent either end of said strips and between the table top --l and the frame -14, and each of these openings or slots 20- are utilized to receive a table extension leaf as --21- when said leaves are not in use.

Each of the extension leaves -2l is of less thickness than the width of the opening -20-- so as to permit the free movement of the leaves into andout of the respective openings. The length of each leaf is substantially equal to the width of the table top land the width of each leaf is made substantially equal to the distance between the spacer strips 2- and the adjacent ends of the table top -lso that when the leaves are positioned beneath the table top, the outer edges of the leaves will be in the vertical plane of the adjacent edges of the table top so that the table will present a neat and finished appearance when the leaves are in the concealed position beneath the table top.

Each of the leaves 21- is hingedly secured to a pair of slide bars --10- hereinbefore mentioned, and which are mounted for longitudinal reciprocative movement beneath, the table top --1- in the slide bar supporting frame -2, each slide bar being positioned in'a respective guide slot 9- of the slide supp'orting frame --4-, as shown more clearly in Figures 2, 4 and 5.

The slide bars -10- are arranged in two pairs, the inner positioned bars constituting one pair, while the outer positioned bars are connected together to form the other pair.

The bars comprising the inner positioned pair of slide bars, are connected at their outer ends by a transversely disposed bar 24- which has the ends thereof positioned in a suitable opening provided in the ends of the slide bars and connected therewith by pins -'25-- or other suitable means. The outer positioned pair of slide bars are likewise connected by a similar cross bar 26- connected with the ends of the respective bars 10 by pins 2'7 similar to the pins for the other pair of bars.

Each of the slide bars 10 is provided with a pair of cavities 29- formed in longitudinal spaced relation adjacent the outer end thereof.

Each of the bars -10 is also provided with a relatively narrow elongated slot 30-- at each cavity 29 and preferably adjacent the outer wall thereof, and which extends below the cavity and beyond either end thereof for pivotally receiving a hinge member --31-.

The hinge 3 1- in this instance, has theupper strap 31- thereof substantially rectangular in plan view and is secured by screws -32- to the undersurface of an extension leaf 21. The other strap as --3l" of the hinge member -3l is formed angular in cross section with one leg as 33 thereof hingedly connected with the other strap member 3l-- constituting the hinge, while the other leg -34 of the strap 31 extends below the leg member 33-- and is provided with an opening 35-- therethrough for receiving a' pin 36-- for pivotally connecting the hinge member to the respective slide bar 'l0-- in the following novel manner: The leg 34- of each hinge -3l is positioned in the slot --30 with the hole 35 thereof in registration with a similar hole3'7-- provided transversely of the bar l0-- beneath each of the cavities 29 as shown more clearly in Figures 6 and 7. The other or shorter leg member 33- is positioned in the respective cavity 29 in such a manner that when the leaf 21- carried by said hinge is in the raised position, the leg member 33- will contact with the outer end 29'- of the respective cavity 29 for limiting the outward movement of said hinge and leaf, and when said leaf is moved to the lowered position in contact with the upper face of the supporting slide bars 10-, said hinge will register in the respective cavity 29.

It will therefore be seen that each leaf is provided with four hinges 3 l connecting said leaf with the respective pair of slide bars --10 and that when the leaf is in the raised position, it will be securely maintained therein against outward movement by the hinges contacting with the outer wall of respective cavities 29.

The slide bars 10' are of such a length that when the bars are moved outwardly to bring the leaf carried thereby into co-operative relation with the adjacent end of the table top 1--, the inner ends of said bars will be in registration with the slide bar supporting frame 4, as illustrated more clearly in Figure 5, while the outer ends of the bars are supported by the adjacent end member 16- of the frame 14 and which are provided with suitable slots or recesses 40 or 40'-- in the upper edge thereof, for receiving the slide bars therethrough, said slots being of such a depth as to engage the ion undersurface of the respective slide bars 10 to form a rigid support for the outer ends of the slide bars, and also for the table leaves when said leaves are in the operative position in contact with the respective ends of the table top 1.

In operation, considering that the table leaves are in the concealed position beneath the table top l--, it is only necessary for the operator to grasp the tie bars -24- and 26 and draw the leaves and respective supporting slide bars, outwardly a sufficient distance to bring the 'extension leaf connected therewith beyond the outer end of the table top l-. Then, by rocking the leaf 21- upwardly about the axis of iio the pivotal pins 36-- until the strap 31 of the hinge 31- engages the outer ends 29- of the respective cavities 29, the leaf 21 will bebrought into the plane of the table top --1. Then, all that is necessary to bring the leaf into co-operative relation with the table top, is to move the slide bars 10- together with the leaf --2l carried thereby, inwardly until the inner edge of the leaf engages the outer adjacent endof the table top 1.

its

It is now evident that the table leaves 21--" will be maintained in a rigid and secure manner in co-operative relation with the table top 1 due to the fact that the supporting hinges -3lare prevented from rocking outwardly about the pivotal supports 36- by the end walls of the cavities 29, while the leaves are prevented from moving inwardly due to theirengaging relation with the table top land that the leaves are maintained against downward movement by the rigid support which the end members 16- supporting frame, of a table top fixedly secured to said frame to extend over the entire upper surface thereof, an extension leaf normally positioned beneath the table top, slide bars supported for longitudinal movement by the table top and by said frame each bar being provided with longitudinally spaced cavities and an elongated slot at each cavity of greater depth than said cavity, and hinge members connecting the leaf with said bars whereby the leaf may be moved into the plane of the table top when said bars are in the extended position, each of said members including a hinge strap secured to the leaf and a second strap comprising a pair of legs of unequal length arranged at right angles to each other, the shorter of said legs being positioned in the cavity and the longer leg extended into the slot and a pin pivotally securing the longer leg to the slide so that when the shelf is raised to the operative position in the plane of the table top, the shorter leg will abut against one end of the cavity for limiting the outward swinging movement of the hinge strap and maintaining the leaf in the plane of the table top, and when the leaf is in the inoperative position beneath the table top, the entire hinge will lie within the cavity below the upper face of the slide.
